I'm getting excited!

right wing:

well, let's see if i can make it work.

if i build another, i know now what i've done wrong. (i built the thing "backwards" basically, e.g., in the wrong order of fitment and such.)

but, it is kind of interesting to see if i can get it to work even after doing everything bass ackwards, so to speak.

john jay

p.s. thanks for the read, and thanks for the comment.

friends:

i've been doing a little reading on drills/drill bits and mills/end mill bits, etc.

a drill press ain't gonna cut it for want i want. not without endless hours of coaxing the product into rough "compliance" with an acceptable end product.

gonna have to get a mill for the tolerances i want. just gonna have to "man up," sell some stuff, do without some stuff, get used to lots and lots and lots and lots of oat meal, and get a little mill.

and, some mill bits. and, center bits.

that's all there is to it. drill bits just go all over everywhere. "walk about," is a pretty good term here.

Did you rough up the back side of the stainless, so that the epoxy would get a good purchase? A good course sand blasting would probably work best. Though a D/A sander with 36 grit might be just as good.
The problem with drilling SS is it work hardens - that is, the metal actually gets harder as you drill it. Sharp tooling and good cutting fluid are absolutely essential.
I know it wouldn't be aesthetically pleasing, but have you considered using through bolts to hold the cladding to the laminate? Strategically placed sex-bolts would lend strength, while not detract too much from the looks. Socket head cap screws, of the correct size- with an acorn nut, could possibly take the place of some of the pins as well.
I'm really looking forward to the function test.

well, let me see. i'll just reply question by question.--

rough up stainless. yes, i sanded the stainless before application of the epoxy, a brand called dev con, i believe. i think it might have been o.k., but, i did not apply enough pressure to it as it cured. and, when i drilled, it was the side "opposite entry" the de-laminated, from the pressure of the drill.

sharp tools. i used new "cobalt" drill bits, but, the bits just walked on the opposite side as i drilled. not good!!!

through bolts. yes, i endorse and "accept" this idea. i was going to/will use through bolts for the various pins, and i will add some to the front and back of the receiver.

it will give things a sort of "frankenstein" appearance, but, i don't care. and, for years, machine guns have been held together with bolts. since my receiver is "squarish" as opposed to "roundish," i think it will look appropriate, in an odd sort of way.

socket head caps, i think, as i can source them locally quite easily.

function test. everybody thinks it will "blow up." not a chance.

but, it may de-lam. we'll see, but, i think it will hold together. everybody forgets the strength of wood. it's pretty amazing stuff.

nature's "carbon fiber," when you get down to it. (o.k., maybe not quite as strong as real carbon fiber, but, it is stronger than steel by weight.)

thanks for the read, and thanks for the suggestions.

john

p.s. i've been reading up on epoxies, and the e-6000 series sounds interesting to me. i've got to see if i can source it here, though we do have ace hardware which is supposed to carry it.

I have no doubts she'll run just fine, once you get it sorted out. No worries on strength either; if they can make lowers out of recycled milk jugs, then I wouldn't worry a bit about yours.

All the places I have ever seen selling 80% receivers and jigs advise against drilling through from one side - just because of drill walk. A straight flute, solid-carbide drill might be up to the task. Then finish the hole to final size with a chucking reamer.

I hope I'm not coming off like I'm telling you, your business. I'm just enthusiastic about this project. I have an idea for making your assembly using a jig, if you are interested. Just let me know at the address in the comment form. I'll work up my idea, and present it to you Monday - if you would like.

Look forward to seeing her go bang!

"tell" away. i am always receptive to information on how to do things, especially when it concerns subjects that i don't know much about.

i am learning first hand about "drill walk," however, and it would be nice to know how to drill a nice straight hole through laminated material.

i like you enthusiasm.

just leave an email address for me ... i'll delete it from the comments, and then contact you.

i am reluctant to print my email address on a public place like the comment forum.

I thought that my email would have been visible to you already? I guess I'm confused as to the purpose of submitting it in the comment form. Just so long as this gets scrubbed off fairly quickly - I get enough spam......>>

Talk to you soon.

i went to my email, i search the personal file, and the other files.

i even went through my facebook and linkedin notices, and saw nothing from you.

(i never look at the damn thing, i've not figured out what in the hell they are about, except a place to show all the pictures your kids won't look at.)

i would respond, if i knew your email address.

john

p.s. i get enough crank and spam mail as it is, without publishing mine.

Leigh

John

I don't know what happened, I posted my address yesterday. I think the site scrubbed it off before it got to you. So we'll try it again.
Lets see if the IT weenies thought of this:

Lima Golf Hotel, Alfa Tango, duramill, Delta Oscar Tango, Charlie Oscar Mike.
I think you should be able to figure that out easy enough. :)

Yeah, I have no use for Fake-book myself. I sure as hell won't let my kids get on there either! I've been invited to LinkedIn, but I'm not quite sure of the value of it.
I do understand your desire for PERSEC and privacy. I share those feelings, myself.

got it. i've make the initial "cipher," and will try in a bit.

i am going to "unpublish" the comment, but, i've got it archived.

should be contacting you in the next day or so. errands, bill paying, walking to take care of this day. and, the usual massacre session w/ the guitar tonight.

Excellent. I look forward to it.
